FOLDING BOX.

SPECIFICATION forming part of Letters Patent No. 642,121, dated January30, 1900. Application tiled May 20,1898. Serial No. 681,207. (No model.)

,To @ZZ whom, it 72mg/ concern:

Beit known that l, HERBERT L. HILDRETH, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Folding Boxes, ofwhich the following is a specication.

My invention relates to that class of boxes commonly made of pasteboard,which are so constructed that for purposes of packing and transportationthey may be folded iiat and subsequently be converted into the ordinarybox forni. lts object is to improve the construction of these devices iucertain particulars, which will be hereinafter more fully pointed out.

ln the drawings lhave shown, in Figures l, 2, and 3, the blanks of whichthe box is composed, at Fig. 4, in perspective, the section of the boxthat forms the outer sides and tops, at Fig. 5 the other section of thebox, consisting of the inner sides and bottom, and at Fig. 6, likewisein perspective, the whole box formed by engaging the sectionsillustrated in Figs. 4 and 5 one with the other, the box being open.

The blank A, Fig. 1, comprises the part 1, which is the outer rear sideof the finished box, the part 2, which is the box cover or top, and thepart 3, which is the top-securing flap. The blank B, Fig. 2, consists ofthe part 4, which forms the outer front of the completed box, the parts5 and G, which form the outer ends or end sides thereof, andthe parts 5ando, which constitute two locking-flaps. The function of these will bemore fully explained later. These two parts A and B, put Y together,(see Fig. 4,) form one section of my improved box, which, as is obvious,is composed of the sides and top of the box. My preferred method ofsecuring said blanks together is by means of flaps 1fL and 1b, formedupon the part 1 of the blank Aand pasted onto the end of parts 5 and 6.Obviously, however, these iiaps might be formed upon the parts 5 and 6and pasted on the part 1, or the blanks A and B might, although not soeconomically, be cut from a single piece of stock, either the part 5 orthe part G being made integral with the part 1, and thereby only onejoining-flap being required.

The blank O contains the portion 7, which forms the bottom of theFinished box, and the portions S, 9, 10, and 11, which respectively formthe inner parts or faces of the ends and inner front and rear sides ofthe box. The parts 10 11 are each provided with a locking flap, (marked101L and 11a, respectively.)

The blank O forms the second or, as it might be termed,the in nersection of myimproved box, the other or outer sect-ion being, as pointedout above, formed by uniting the blanks A and B.

It will be seen that both of the box-sections can be folded into a flatform. This is of great importance, as it enables a relatively largenumber of the box-sections to be packed into a small compass forshipment, and any party can readily cause each section to assume itsproper form for use and assemble said sections to provide a completebox.

ln assembling the sections that one formed from the blank C is placedwithin the other, (formed by the blanks A 13,) and the flaps 10*L lla ofsaid inner section are caused to overlap the flaps 5n 6a of the otherbox-section, as shown clearly in Fig. 6. Vhen l[he parts have been thusassembled, although no rigid or permanent connection is establishedbetween the two sections, it becomes practically impossible when the boxis filled and the cover folded down and secured by inserting thetopsecuring flap 8 into the pocket formed between the parts 10 and 4towithdraw or separate one part or section of the box from the other. Atthe same time the four ilaps 5a, 6, 10, and 11' form a border about theopen end of the body of the box and presenta neat iinish when the top isopen and the contents exposed.

The parts 8 and 9, which l have heretofore spoken of as constituting theinner end sides of the box, are preferably, although not necessarily,made as wide as the corresponding parts 5 and 6 of the outerbox-section. The

function of these parts 8 and 9 is mainly to close the joint which wouldotherwise occu r bctween the bottom and the end sides of the box. Ibelieve it,however,to be advantageous to extend them up to the sameheight asthe other corresponding portions, both for the sake ofuniformity and also because I thereby IOO vss

obtain a box which has all four sides double, and hence is ofcorrespondingly-increased stiffness.

From the above description and the drawings it will be seen that I haveprovided a box consisting of two independent and separately-formedsections adapted to be detachably connected, each section being of suchform as to be capable of folding upon itself into a practically fiatcondition.

The advantages incident to such a construction in comparison with boxesof the same general character and for analogous purposes heretoforeproposed will be apparent. As all of the parts required to bepermanently connected by pasting or other similar means are connected informing the sections, the party desiring to use the box need not beskilled nor have to employ any special means for securing the twosections together.

I am aware that prior to my invention of the box herein illustrated anddescribed it has been proposed to make a box from two paper blanksproperly folded and secured together to form the vwalls of the box; butin all of the earlier constructions with which I am acquainted it wasimpossible to separate the completed box into two independent sectionsat any time after they had once been assembled-that is, in the earlierconstruction above referred. to the sections or blanks from which thebox was formed werevpermanently secured ,together and could not beseparated without damaging and destroying the further usefulness of thearticle. By my invention, however, it will be seen that the two sections(one formed by the blanks A B and the other by the blank C) are entirelyindependent and distinct one from the other, and there is no suchpermanent and fixed connection between said sections as prevents theirseparation at any time.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The herein-described folding box having double side and double endwalls and consisting of two independent sections, onesectionV formingthe outer side and end walls and the cover for the box and the othersection forming the inner side and end walls and the bottom of the box,the latter section being fitted within the first-named section, and saidsections having at their upper edges means for engaging with each otherwhereby the sections are held together when the box is in use.

2. A folding box having double side and double end walls',com posed oftwo distinct and separable parts, one part comprising the outer side andend walls and the top, and the other part the inner side and end wallsand the bottom of the box, the said last-mentioned part being fittedwithin the first-mentioned, the side walls of one part being providedwith flaps, and the end walls of the other part being provided withsimilar flaps adapted to interlock therewith when the two parts aretitted together, for the purpose set forth.

3. A folding box having double side and double end walls consisting oftwo detachable and separately-constructed sections, one section formingthe outer side and end walls, the cover of the box and a flap on thefront edge of said cover, and the other section forming the bottom ofthe box and the inner side and end walls, the end walls of the firstsection having inwardly-extending flaps, 5a, 6, at their upper edges andside walls of the second said section having at their upper edgesinwardly-extending fiaps, 10, lla, adapted to rest on the flaps, 5, 6,and to support the second section within the first-mentioned section.

4. A folding box of the character described composed of three blanks,oneforming the top and one of the sides of the box, another connected tothat aforesaid and forming the other side and the ends of the box, andthe third forming the bottom of the box, the two lastnamed blanks beingprovided with flaps adapted to overlap and connect said parts together.

5. The herein-described box embodying in its construction three blanks,A, B, C, the blank A forming the'back side wall, l, and the cover, 2,the blank B forming the front wall, 4, and end walls, 5, 6, and adaptedto be secured firmly to the blank A, the end sections 5, 6 of the blankB having the inwardlyextending fiaps, 5a, 6a, at their upper ends, andthe blank C forming the bottom of the box and having upwardly-extendin gportions, 10, l1, terminating in fiaps, 10a, lla, which engage with theaforesaid flaps, 5a, 6a.

6. The herein-described box having double sides and embodying in itsconstruction three blanks, A, B, C,.the blank A forming the outer part,1, of the back side wall and the cover, 2, which is provided with aretaining-flap, 3, the blank B forming the outer parts of the front sideand end walls and adapted to be firmly secured to theblank A, the endsections, 5, 6, of the blank B having inwardly-extending flaps, 5, 6a,at their upper ends, and the blank C forming the bottom of the box andthe inner parts of the side and end walls thereof, the inner parts ofthe side walls having at their upper ends inwardly-extending flaps, 10a,lla, which overlap the aforesaid flaps, 5, 62.

In testimony whereof I have hereunto subscribed my name this 13th day ofMay, 1898.
